Answer:
18+12.125π units²
Step-by-step explanation:
The diameter of the semicircle can be found by the use Pythagoras theorem.
Δx²+Δy²=d²
Δx=3--1=4
Δy=3--6=9
d²=4²+9²
d=√(16+81)
Area=πr²/2
=π×(√(16+81)/2)²÷2
=[π×(97)/4]/2
=97π/8
=18+12.125π units²
97π/8 is equivalent to 18+12.125π units²

This would be an exponential graph and non of the answers are exponential. but the graph would be f(x)=3^x
Answer:
Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75
Step-by-step explanation:
Let the cost of paint set be = p
Cost of sketchbook 's' = (2 / 3) p
Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p
Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25
Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b
= p + (2 / 3) p + (1 / 6) p = 19.25 → p + 2p / 3 + p / 6 = 19.25
( 6p + 4p + p ) / 6 = 19.25 → 11p / 6 = 19.25 → p = ( 19.25 x 6 ) / 11
p = 10.5 ; s = (2 / 3) p = 2 / 3 (10.5) = 7 ; b = (1 / 6) p = 10.5 / 6 = 1.75
